Right-to-left Support
The RadRating fully supports right-to-left (RTL) language locales. In order to turn on the RTL support you should set its IsDirectionReversed property to true as well as dir=rtl to the html or body elements or to its direct parent.
<div dir="rtl">
<telerik:RadRating RenderMode="Lightweight" ID="RadRating" runat="server" ItemCount="7" IsDirectionReversed="true">
</telerik:RadRating>
</div>
